Modelling scenarios of technological risks and disasters due to natural gas condensate explosion
| Resumo: | The changes in society following the Industrial Revolution have driven the global economy, particularly in the oil sector, which has seen significant growth with the increased use of natural gas since the 1970s. Industrial activities involving the handling of liquid gas can result in technological disasters known as boiling liquid expanding vapour explosions (BLEVEs). Computational modelling is an essential tool for identifying the potential scope of these disasters, contributing to emergency training and environmental management. This study aimed to simulate the explosion of natural gas condensate stored in an industrial pressure vessel containing approximately 37 m3 of gas. The deductive method was used, gathering geographic and climatic data and establishing risk scenarios modelled in version 5.4.7 of the Areal Locations of Hazardous Atmospheres (ALOHA) software. The results indicate that, in all analyses, the explosion radii were greater than one kilometre, covering a potentially lethal zone, including the pressure vessel facilities and the surrounding ecosystem. Despite the limitations of the platform, ALOHA made a preliminary analysis of the consequences of BLEVEs possible. |
